The correct answer is: C. Solar power
Solar power is the most abundant renewable energy source on Earth. The sun’s energy can be converted into electricity using solar panels or mirrors. Solar power is a clean and sustainable source of energy that does not produce greenhouse gases.
Water power is the second most abundant renewable energy source on Earth. Water can be used to generate electricity using hydroelectric dams. Hydroelectric dams can have a negative impact on the environment, so they are not always a good option.
Wind power is a clean and sustainable source of energy that does not produce greenhouse gases. However, wind power is intermittent, meaning that it is not always available.
Biomass power is a renewable energy source that comes from plant material. Biomass power can be used to generate electricity or heat. However, biomass power can have a negative impact on the environment if it is not managed sustainably.
In conclusion, solar power is the most abundant renewable energy source on Earth and has the largest potential. Solar power is a clean and sustainable source of energy that does not produce greenhouse gases.
